CO2 Non Blowback Pistols. Take your pick: there's a variety out there.
CO2 is efficient because:
1. It's cheap. Unlike green gas that is usually bought online, not through your local sporting goods store.
2. It's powerful. You will get more shots per CO2 cartridge than one fill up of green gas.
Definitely a gas pistol, You don't have to cock it between each shot
Neither, all guns are violent and dangerous.
Yes, any airsoft weapon should be lubricated properly.

It is possible.
Electric pistols are not powerful. If you want power, I would recommend a green gas pistol.
Needs to be serviced
It all depends what your first one is and the quality of it. If your first Airsoft Gun is a AEG, then you should probably but a decent gas pistol for backup. If you decided to become a sniper and you bought a sniper rifle as your first gun then you should look into small battery powered AEGs such as MP5Ks or MP5s. But overall, a good gas pistol would be an overall upgrade to anyones arsenal.
Varies by the pistol. Normaly better than spring.
I would. But get a good one. Airsoft pistols are bad to jam.
depends what model but usually one mag worth
